The current debate isn't really on whether antidepressants cause suicide, but rather which antidepressants cause it more often! In a recent article in Medscape medical news, that issue was seen as an important part of a Finnish study, which was originally published in the Archives of General Psychiatry.
"Among suicidal subjects who had ever used antidepressants, the current use of any antidepressant was associated with a markedly increased risk of attempted suicide..." according to the article.
This study and most others still ignore the obvious link between antidepressants and homicide/violence. But it's a step in the right direction.
The effect is being felt, too. Yesterday the FDA stated that they are expanding the "black-box" warning label on antidepressants to include young adults as potential victims of suicide or suicidal thinking. This is a BIG step in the right direction. There has been a black box warning (so called because it must be in a black box on the product) warning about this reaction to the drug in children and young adults for several years already.
